REINFORCED-CONCRETE WATER PIPE OR CONDUI'I.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application' filed July 23, 1906. Serial no. 327,357.

To all whom it may concern:

.the object of the invention is to construct such a pipe of unusual strength.

I The invention consists in taking a plurality of tubes of steel, galvanized iron or other suitable material, which tubes are adapted to telescope at their ends, and providing the said tubes with inner and outer layers of concrete or other form of artificial stone, and also in providing means which will prevent movement of the pipe covering, that 15 of the concrete, upon the pipe.

In thedrawings forming a part of this specification ':Figure 1 isa side elevation of a pipe constructed in accordance with my invention and completed with the exception of filling grooves at the point of juncture of the tubes. Fig. 2 is a perspective view of an epd portion of one of said tubes with certain ties in place. Fig. 3 IS a section taken transversely through a wall of one of my p pes showing one of the ties partly in elevation,

and partly in section. Fig. 4 is a detail perspective view of one of the ties, the two parts of the tie being shown detached. Fig. 5 is a section through a wall of one of the tubes showing a modification of the ties. one tie being shown with one part in elevation and the otherpart in section. Fig. 6 is a longitudinal 'section through a completed pipe. Fig. 7 is a transverse section through a pipe. Fig. 8 is a section through a portion of a pipe taken adjacent the ends of two telescoping tubes. Fig. 9 is a transverse section through a pipe showing a slight modification 1 in the construction of the tube. Fig. 10 is a detail view of a portion of one of the tubes shown in Fig. 9.

In these drawings A represents a tube which is preferably of steel or galvanized iron but which may be of any suitable water proof material and this tube is provided with a plurality of openings which are drilled in it and through which passes suitable ties B, .empleyfi for the purpose of binding the concrete securely ,to the tube and .preventing the concrete slipping in any dircction upon either the outer or inner surfaces of the tube. These ties as shown in Fig. l, are preterit ly formed of a shank B provided it'ittr fla tire'aded socket anchof' a shank B i rovitlcd with a threaded portion B which engages the socket ot' the shank B. Both shanks are expanded as shown at, 13* to provide bearing surfaces to rest upon the inner and outer faces of the tube A, respectively, and both'the shank B and the shank ll are provided with suitable heads.

In Fig. 5 I have shown a slightly modified construction which avoids the use of the threaded portion B. In the construction shown in Fig. 5 the tie is formed of a sleeve C and a'shank C which is provided with a. pin (3 which passes entirely through the slceve C and is expanded or riveted as shown at C at its upper end. Otherwise, the construction is the same and the only practical dill'crence that one form of "tie has its separate parts connected by screwing them together while the other form of tie has the two parts riveted together.

Upon the inner face of each tube A is placed a layer of concrete D, which surrounds and entirely embeds the inner portions of the ties B. The concrete D extends flush with one end of the tube A so that. when the tubes are joined the concrete D extends continuously through the pipe. Upon the outer face of each tube is placed a layer of concrete 1) which also embeds the outer portions of the ties B butwhich terminutes short of cach end of the tube. It will be obvious therefore that when the tubes with the concrete applied thereto, are joined together by telescoping-their end portions a plurality of-circinntercntial grooves will be left upoiithe outer iuocof the pipe. In each of these {grooves fitted a ring which consi ts of a wire rod ll threaded adjaccnt each end and a. washer E is formed ot' a block which tits withinthe grooves and which is provided with oppositely arranged passages and through these passages the end ortions of the wire E are passed, said portions overlapping each other. Nuts E' are threaded upon the projecting end portions of the wire E whereby it is drawn over tightly about the tubes A and firmly bind their telescoping end portions together. The groove is then filled with concrete as shown aiiords both inside and outside a smoothsurface of concrete or artificial stone.

In Figs. 9 and 10 I have shown a slight modification in Which I employ a tube F provided with a plurality of depressions, which depressed portions reject inwardly taking the place of the ho es drilled in the pipe A and'o he ties B. The inner layer of concrete has the depressed portions F sunken into it, while the outer layer D enters and fills the depressions themselves. These depressed portions therefore, form ties integral With thetube.

Having thus fully described my invention, What I claim as new and desireto secure by Letters Patent, is

1." In a pipe of the kind described a tube, a

plurality of inwardly and outwardly extendin sectional telescoping ties carried by said tu e, and inner and outer layers of concrete applied to the tubes and covering the said ties.

2. A pipe of the kind described comprising a tube of Water proof material having openings formed therein, atie consisting of a shank having a socket, a shank having a pin adapted to engage said socltet, said pin passing through the Walls of the tube, and layers of concrete arranged upon the inner and outer face of said tube and covering the said tie.
